Bug #2370

Forked process generates spurious signal errors

Added by Chris Schlaeger about 6 years ago. Updated over 4 years ago.

ruby -v:ruby 1.9.2dev (2009-11-10 trunk 25704) [x86_64-linux] Backport:


The attached test program demonstrates the problem. About 25% percent of the time the forked-off program terminates with a signal error.

For best results the first parameter of the doRun() call should be set to a value slightly higher than the number of CPU cores in the system.

Ok: 1513 Errors: 487

real 1m21.352s
user 1m3.712s
sys 0m20.913s

The terminated processes are killed during the IO operation and leave test*.txt files of varying size in the current directory.
The program works fine with ruby 1.8.7 PL27.
